Blastocyst transfer

Blastocyst Transfer is a technique that was introduced in 1988 by Stanford University. Embryos formed as a result of fertilization are cultured in the laboratory for 5-6 days. In this time, the cells of the embryo rapidly divide and on day 5 it is referred to as a Blastocyst.

Transferring a 5-day-old embryo or Blastocyst into a woman’s uterus may improve the chances of implantation and in turn, a successful pregnancy. It also reduces the risk of multiple pregnancies, which is a problem with Assisted Reproductive Techniques (ART) and which pose medical risks for both the mother and the infant along with financial and emotional considerations.
